A choice subform set is a variation of the subform set object that allows you to customize the display of specific subforms from within the set through the use of conditional statements. As with subforms sets, choice subform sets are bound to data from a data connection. However, using choice subform sets provides a greater level of control over which subforms within the set are displayed at run time. For example, you can configure a choice subform set to display instances of a repeating subform by using different text colors, depending on the value of a specific field within that repeating subform.
